Tips

Tip 1

Bring fish to cool room temperature 10 minutes before grilling for even cooking throughout. Cold fish from refrigerator may char outside before inside cooks through.

Tip 2

Don't skip discarding the marinade. The raw fish liquid can harbor bacteria if reused for sauce or basting during cooking.

Good to Know

Storage

Wasabi butter keeps refrigerated up to 3 days in airtight container. Halibut is best consumed same day but leftovers store 2 days covered.

Make Ahead

Prepare marinade and combine fish with liquid up to 4 hours ahead. Make wasabi butter up to 1 day ahead and let reach room temperature before serving.

Serve With

Serve immediately on warm plates with steamed bok choy, jasmine rice, or roasted asparagus. A crisp sauvignon blanc or light pilsner complements the wasabi heat and citrus notes.

Common Mistakes

Watch

Marinate longer than 4 hours to avoid over-curing the delicate fish flesh and mushy texture.

Watch

Skip turning fish only once to prevent drying out and breaking apart on grill.

Watch

Discard marinade before cooking to avoid bacterial contamination from raw fish.

FAQ

Can I use frozen halibut without thawing?

No. Thaw completely in refrigerator for 24 hours before marinating. Frozen fish won't absorb marinade evenly and cooks unevenly, resulting in dry exterior and raw center.

What if I don't have a grill?

Pan-sear in cast iron over medium-high heat for 4-5 minutes per side, or bake at 400°F for 12-15 minutes. Broiling 4 inches from heat for 8-10 minutes also works well and mimics grill char.

How long can I keep leftover grilled halibut?

Store covered in refrigerator up to 2 days. Reheat gently in 275°F oven or eat cold in salads. Freezing cooked fish is possible but texture degrades significantly upon thawing.
